To all whom 'it 'may concern:

Be it known that I, CHARLES J. G. KEINER,- a citizen of the. UnltedStates, residing at Baltimore, in the State'of Maryland, have invented'certain new -and useful Improvements in Connectors for Elect-ric Wires,of which the following is a specification.

This invention relates to im )rovements in connectors forclectricwiresandhas particular reference to a two part and a two-way insulatedconnector'by whichthe ends of the conductor wires. may be brought -intoelectrical connection vand securely held against accidentaldisplacement.

The device is particularly well adapted lfo'c use on motor cars wherethe connector is su h jccted to vibration in that the-use. of bindingscrews is avoided and all liabilitv of the connection being broken bythe screwslworking loose.

The' invention is illustrated in the accompapving drawing, in whieh,-

l proved device o eratively connected.. Fig.

i 2 illustrates a si( e elevation 'of the two parts of the connectorseparated.- Fig. 3 shows' a .longitudinal sectional view of the device.

Fig. 4-illustrates a similar view of.a slightly modified form of device.'Fig. 5 shows an end'view ofthe plug or insertible'memberof theconnector, andFig. 6 illustrates acrosssectional viewofthedevice-fthesection bcing taken on the line 6 6 of Fig. 3.

Referring to thedra'wing by numerals, 1.,

.designates the socket-member ol the device and, 2, theplug-member.thereof, it being understood that the completed eonnect orcom prises two parts, oneoi which fits into and en ages the other.`

he socket-member, l, comprises an inner metal bushing, 3, having atape-red rer-.ess

or chamber, 4, extending longitudinally ,therein and a .centrallongitudinal iassage,

' 5, which extends from the outer en of said bushing and o ens-into thesmaller end of said recess or e lamber. The inner or larger end of thisbushing is .provided with a series ol' longitudinal slots, 6, formingspaced-apart.

fingers, 7, at said end, as'scen in Fig. 2.

A sleeve, 8, of insulating material surrounds thc bushing and forms acovering therefor. This sleeve is longer than the bushing and' projectsbeyond the outer end thereof while the inner end of said insulatingsleeve is provided `with spaced-apart ingers. -9, which project over and'coverthe'fin gurc 1 shows a side elevation of the im- Awhen the twomembers are connected,

gers, 'Lol' the bushing. "lhese fingers, 9,-.are rovided with beveledends, 10, whereby to orm acom'plcteand, tight covering when en# agingthe socket member as will presently Je described.. A circumferentialgroove, l1, is provided -on the exterior of each of the fingels betweenthe two' ends of said fingers.

The wire, l2,to be connected to the socketmember, 1, is passed throughthe central passage,.5, ofthe bushingand projected into the chamber,4,'v and a tapered thimble or shell, "1'3, is then insert-ed 'overtheend of thc'wire,

and the latter is then secured in sajid thimble,

preferably by means of solder, 14, which'is poured into thc thimble. Bvthis means the wire is secured in the thimble or shelland can not. bedrawn back through the passage, 5. The plug-member, 2, of the connectoris valso provided with a metal bushing, 15, having a longitudinalcentral chamber, 16, and

into .said chamber. 'lhis bushing is-pro vided at. its inner end with apluralityv of L i lon yitudinal slots 18, formin 'a `iluralit of f g yylc dunr or spring hngcrs, .19, wnch latter pro'eet intothe la credrecess, 4, of the soclietmwmlwr bus ling and will contact with the wallsthereof. f 'lhe wire, 2U, to be connected to the plugnrember passesthrough the passa eway, 17,l

and is secured -bv solder in n. thimb e or shell,

2l, in tlul chamber, '16.

An insulating sleeve or covering, 22, surrounds the outer end of theliushing, I5, b'ut lea-ves the yielding lingers,i 19, uncovered. T hissleeve, like the sleeve, 8, of the socketmember, is provided withspaced-apart fin gers, 23, having beveled ends, 24, and. cir- Af ter thewires have had their ends secured in the two members the plugmember willthen lie-inserted in the socket-member and the. two pushedl together-un'til'the fingers of one will fit between the fingers of the other'100.

and the beveled ends of the fingers onone member will project beyond-theInner en ds of the fingers of the other member, thus iin-- suringaperfect covering for the two mem bers, as can beseen in Fig. 3. When thetwo gerswill aline and. form a continuous groove 75. a passageway, 17,at the outer lend leading io 7' 'members have thus been interlocked thecir- Q currferential grooves on the two sets of finwound around theinterlocked fingers and in the ooveland serves to prevent the two memers from being se or,otherwise. It'wlll t ius be seen thatthe connectionof the two wires is mede without em loying screws or devices of anycharacter" which may work loose by vibration.

In the device shown in Fig. 4 the modiiication consists only in themanner of securing the wires in the bushings. Inthis device l endrecesses, 27, are provided in the bushings, 28, and the wires aresecured ln said recesses by pouring solder, around the wire.

Having thus described my invention what 2S), ltherein and I claim asnewand desire to secure by Letters Patent is,

1. An-electric wire connector having a socket-member and a plug-member;an 1nsulating covering around each of seid members and the adjoiningends of said coverings havingintermeshing lingers and means for en agmgthe 'lingers on the two coverings to hod the members together.

2. An electric wire connector having a socket-member and a plug-member;wires attached to said members; en insulating covcoverings havingiingcrs and euch linger being provided wlthan exterior groove winchlatter when the two members are joined, will register and form acontinuous circumferential groove around the two members, and

means extending, around the grooves of all arated by vibration.

of said fingers to'hold the coverings and members together. -f f 3..-Xrrfalctric wire connector having a socket-member provided at one endwith lingers; n'wire connected to said socket-meni- 'kber a {dug-memberhaving a yielding plug to enter the. socket-member and also havingiingers to mtermesh with the lingers of the socket-member; n wireconnected to the plug-member, and means engaging the lin# gers of 'bothmembers to lock the two together.

"In'testnnony whereof l-allix my signature vin presence of twowitnesses.
